AND THERAPEUTIC AND PROPHYLACTIC USES THEREOF Background of the Invention Throughout this application, various publications are referenced by Arabic numerals. Full citations for these references may be found at the end of the specification immediately preceding the claims. The disclosure of these publications is hereby incorporated by reference into this application to describe more fully the art to which this invention pertains. The life cycle of animal viruses is characterized by a series of events that are required for the productive infection of the host cell. The initial step in the replicative cycle is the attachment of the virus to the cell surface, which attachment is mediated by the specific interaction of the viral attachment protein (VAP) to receptors on the surface of the target cell. The differential pattern of expression of these receptors is largely responsible for the host range and tropic properties of viruses. In addition, an effective immune response against many viruses is mediated through neutralizing antibodies directed against the VAP. The interaction of the VAP with cellular receptors and the immune system therefore plays a critical role in infection and pathogenesis of viral disease. The human immunodeficiency virus type 1 (HIV-l) infects primarily helper T lymphocytes, dendritic cells, and monocytes/macrophages--cells that express surface CD4-- leading to a gradual loss of immune function. This loss of function results in the development of the human acquired immunodeficiency syndrome (AIDS) (l) . The initial phase of the HIV-l replicative cycle involves the high-affinity interaction between the HIV-l exterior envelope glycoprotein gpl20 and cell surface CD4 (K d approximately 4 x 10 "9 M) (2) . Several lines of evidence demonstrate the requirement of this interaction for viral infectivity. The introduction into CD4" human cells of cDNA encoding CD4 is sufficient to render otherwise resistant cells susceptible to HIV-l infection (3) . In vivo, viral infection appears to be restricted to cells expressing CD4, indicating that the cellular tropism of HIV-l is largely determined by the pattern of cellular expression of CD4. Following the binding of HIV-l gpl20 to cell surface CD4, viral and target cell membranes fuse by a mechanism that is poorly understood, resulting in the introduction of the viral capsid into the target cell cytoplasm (4) . Mature CD4 has a relative molecular mass (Mr) of 55 kDa and consists of an N-terminal 372-amino acid extracellular domain containing four tandem immunoglobulin-like regions (V1-V4) , followed by a 23-amino acid transmembrane domain and a 38-amino acid cytoplasmic segment (5, 6) . In experiments using truncated sCD4 proteins, it has been shown that the determinants for high-affinity binding to HIV-l gpl20 lie solely within the N-terminal immunoglobulin-like domain (VI) (7-9) . Mutational analysis of VI has defined a discrete binding site (residues 38-52) that comprises a region structurally homologous to the second complementarity-determining region (CDR2) of immunoglobulin genes (9) . The production of large quantities of sCD4 has permitted a structural analysis of the two N-terminal immunoglobulin- like domains (V1V2) . The structure determined at 2.3 angstrom resolution reveals that the molecule has two tightly-associated domains, each of which contains the immunoglobulin-fold connected by a continuous beta strand. The putative binding sites for monoclonal antibodies, class II major histocompatibility complex (MHC) molecules, and HIV-l gpl20, as determined by mutational analyses, map on the molecular surface (10, 11) . The HIV-l envelope gene env encodes an envelope glycoprotein precursor, gpl60, which is cleaved by cellular proteases before transport to the plasma membrane to yield gpl20 and gp41. The membrane-spanning glycoprotein, gp41, is non- covalently associated with gpl20, a purely extracellular glycoprotein. The mature gpl20 molecule is heavily glycosylated (approximately 24 N-linked oligosaccharides) , contains approximately 480 amino acid residues with 9 intra- chain disulfide bonds (12) , and projects from the viral membrane as a dimeric or multimeric molecule (13) . Mutational studies of HIV-l gpl20 have delineated important functional regions of the molecule. The regions of gpl20 that interact with gp41 map primarily to the N- and C- termini (14) . The predominant strain-specific neutralizing epitope on gpl20 is located in the 32-34 amino acid residue third variable loop, herein referred to as the V3 loop, which resides near the center of the gpl20 sequence (15) . The CD4 binding site maps to discontinuous regions of gpl20 that include highly conserved or invariant amino acid residues in the second, third, and fourth conserved domains (the C2, C3, and C4 domains) of gpl20 (16). It has been postulated that a small pocket formed by these conserved residues within gpl20 could accommodate the CDR2 loop of CD4, a region defined by mutational analyses as important in interacting with gpl20 (17) . HIV-l gpl20 not only mediates viral attachment to surface CD4 molecules, but also serves as the major target of antibodies which neutralize non-cell-associated virus and inhibit cell to cell viral transmission. There are two major classifications of HIV-l-neutralizing antibodies: type-specific and group-common (15). Type- specific neutralizing antibodies primarily recognize linear determinants in the highly variable V3 loop of gpl20. These antibodies act by inhibiting fusion between HIV-l and the target cell membrane, and generally neutralize only a particular isolate of, or closely related strains of, HIV-l. Sequence variation within the V3 loop, as well as outside of this region, permits viruses to escape neutralization by anti-V3 loop antibodies. In contrast, group-common neutralizing antibodies primarily recognize discontinuous or conformational epitopes in gpl20, and possess the ability to neutralize a diverse range of HIV-l isolates. These broadly neutralizing antibodies often recognize a site on gpl20 which overlaps the highly conserved CD4-binding site, and thus inhibits gpl20-CD4 binding. A structural relationship has been demonstrated between the V3 loop and the C4 region of gpl20 which region constitutes both part of the CD4 binding site and part of the conserved neutralization epitopes. It was observed that deleting the V3 loop resulted in significantly increased binding of a panel of broadly neutralizing hMoAbs (neutralizing human monoclonal antibodies) to the CD4 binding site (18) . A major goal in AIDS vaccine development is to develop a vaccine able to protect a subject against the numerous genetic variants of HIV-l that infect humans. Although cell-mediated immune responses might serve to control infection in HIV-l-infected individuals, several lines of evidence demonstrate that protection against infection is mainly mediated by neutralizing antibodies directed against gpl20. Early experiments showed that immunization of chimpanzees with recombinant gpl20 induced a protective immune response against challenge with the homologous HIV-l strain (17) . This protection correlated with the presence of high-titer neutralizing antibodies against the V3 loop of gpl20. In addition, passive immunization of chimpanzees with a V3-loop neutralizing monoclonal antibody resulted in protection against challenge with the homologous HIV-l strain (19) . Although protection against challenge was demonstrated in these two experiments, recent studies have questioned the clinical relevance of these findings. For example, these neutralizing antibodies recognize the V3 loop determinants of a single strain, and not conserved or discontinuous epitopes. Thus, these antibodies lack the ability to neutralize the broad spectrum of HIV-l strains present in an HIV-l population. Furthermore, the challenge virus was the homologous HIV-l laboratory adapted LAI (HTLV- IIIB) strain and not one of the primary isolates that contain considerable gpl20 sequence heterogeneity. Since these experiments showed that gpl20 subunit vaccination induces an immune response effective against only the homogeneous HIV-l strain used as an antigen, it is unlikely that the vaccination regimens used in these studies would be useful in humans. Individuals infected by HIV-l typically develop antibodies that neutralize the virus in vitro, and neutralization titers decrease with disease progression (19) . Analysis of sera from HIV-l-infected humans indicates that type-specific neutralizing antibodies appear early in infection. Later in the course of infection, a more broadly neutralizing antibody response develops. However this antibody response is of significantly lower titer and/or affinity. Fractionation studies of HIV-l antibody-positive human sera reveal that the type-specific neutralizing activity is primarily directed against linear determinants in the V3 loop of gpl20 (20) . There was no correlation found among antibodies between the ability to neutralize divergent. HIV-1 isolates and reactivity to the V3 loop of these isolates. In contrast, the broadly neutralizing antibodies present in HIV-l antibody-positive human sera primarly recognize discontinuous epitopes in gpl20 which overlap the CD4- binding site and block gpl20-CD4 binding. In other words, the broadly neutralizing activity of neutralizing antibodies is not merely the result of additive anti-V3 loop reactivities against diverse HIV-l isolates which appear during infection. Recently, several groups have generated human monoclonal antibodies (hMoAbs) derived from HIV-l infected individuals which possess type-specific or group-common neutralizing activities (17) . The type-specific neutralizing hMoAbs were found to recognize linear determinants in the V3 loop of gpl20. In contrast, the group-common neutralizing hMoAbs generally recognize discontinuous epitopes which overlap the CD4-binding site and block gpl20-CD4 binding. The V3 loop is a highly immunodominant region of gpl20 which partially interacts with the CD4-binding region. The presence of the V3 loop region on gpl20 may skew the humoral immune response away from producing antibodies which specifically bind to the CD4-binding domain of gpl20. Furthermore, the advantages of removing the V3 loop to expose the CD4-binding domain of gpl20 to the immune system would be countered by the fact that the exposed CD4-binding site would still have a high affinity for cell surface CD4. In other words, a mutant gpl20 protein missing only the V3 loop would quickly bind to CD4+ cells and would thus be hampered in generating an immune response against the exposed CD4-binding site. The subject invention provides a mutant HIV-l gpl20 envelope glycoprotein which overcomes both the problems of V3 -.loop immunodominance and of the high affinity to CD4. The subject invention further provides vaccines comprising the mutant HIV-l gpl20 envelope glycoprotein, antibodies which specifically bind to the CD4-binding site of HIV-l gpl20 envelope glycoprotein, pharmaceutical compositions comprising these antibodies, and methods of using these vaccines and compositions to treat or prevent HIV-l infection.

Detailed Description of the Invention The plasmids designated PPI4-tPA-gpl20 LAI and PPI4-tPA-gpl20 JR . FL were deposited pursuant to, and in satisfaction of, the requirements of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure with the American Type Culture Collection (ATCC) , 12301 Parklawn Drive, Rockville, Maryland 20852 under ATCC Accession Nos. 75431 and 75432, respectively. The plasmids PPI4-tPA-gpl20 LAI and PPI4-tPA- gpl20 jR-FL were deposited with the ATCC on March 12, 1993. The subject invention provides a recombinant nucleic acid molecule which encodes a mutant HIV-l gpl20 envelope glycoprotein comprising a V3 loop deletion and a C4 domain (W _ >X) point mutation, wherein X is an amino acid residue other than tryptophan. In the preferred embodiment, X is a valine residue. In one embodiment, the nucleic acid molecule is a DNA molecule. The DNA molecule may be a plasmid. In one embodiment, the plasmid comprises the sequence of the plasmid designated PPI4-tPA. The V3 loop of HIV-l gpl20 envelope glycoprotein is shown in Figure 1. The V3 loop is demarcated by cysteine residues at both its N- and C-termini. As used herein, a V3 loop deletion means a deletion of one or more amino acid residues between the terminal cysteine residues, with the proviso that there must be three or more amino acid residues situated between the two terminal cysteine residues in a V3 loop deletion. These three or more amino acid residues may either be residues originally present in the V3 loop, or exogenous residues. For example, as shown in the Experimental Details section infra, the pentapeptide TGAGH is situated between the two terminal cysteine residues. Variations in the size of the V3 loop deletion illustrated herein are tolerable without affecting the overall structure of the mutant HIV-l gpl20 envelope glycoprotein, as is -.well known to those skilled in the art. As used herein, "C4 domain" means the HIV-l gpl20 envelope glycoprotein C4 domain having the following consensus sequence: X 1 X 2 X 3 CX 4 IX 5 X 6 X 7 X g X 9 X 1 oWX n X 1 Xι ι Xi 5 AXι 6 YX 17 X 18 - PXι 9 X 2 oX 2 ιX 22 X 23 X 2 X 25 X 26 S 27 X 2 gTGX X 3 oX 31 X 2 RX 33 GX 34 , wherein X. = T, I, V, K or R; X 2 = L, I or H; X 3 = P, Q, L or T; X 4 = R, K or G; X 5 = K or E; X* = Q or E; X 7 = F, I or V; X 8 = I, V or M; X, = N, R or K; X 10 = M, R, L or T; X n = Q, R or V; X, 2 = E, K, G, R, V or A; X 13 = V, T, A or G; X 14 = G or E; X 15 = K, R, E, or Q; X 16 = M, V, I or L; X 17 = A, T or D; X 18 = P or L; X t9 = I or F; X 20 = S, R, G, K, N, A, E or Q; X 21 = G or R; X 22 = Q, L, P, N, K, V, T, E or I; X^ = I, V or L; X M = R, K, S, N, G, I, T, E or I; X^ = C or R; X 26 = S, L, I, T, P, E, V, K, D or N; „ = N, K or L; X 2g = I or V; X 29 = L, P or I; X 30 = L or I; X 31 = L or I; X 32 = T, A, I, V or E; X 33 = D or E; X M = G or V. The C4 domain consensus sequence is based on existing C4 domain sequence information from various HIV-l strains, and thus is not necessarily an exhaustive consensus sequence. The conserved tryptophan residue shown in bold after residue Xio is the only conserved tryptophan residue in the C4 domain. As used herein, a C4 domain (W _ >X) point mutation is a mutation of the above-identified conserved C4 domain tryptophan residue to an amino acid residue other than tryptophan. For example, a C4 domain (W ._ >V) point mutation is a mutation of the conserved C4 domain tryptophan residue to a valine residue. In one embodiment, the C4 domain is an HIV-l^i gpl20 envelope glycoprotein C4 domain. The sequence of the HIV- I LAI g l20 C4 domain is: TLPCRI QFINMWQEVGKAMYAPPISGQIRCS- SNITGLLLTRDGG. The mutant HIV-l gpl20 envelope glycoprotein may be a mutant HIV-l^ gpl20 envelope glycoprotein. In another embodiment, the C4 domain is an HIV-I JR .^ gpl20 envelope glycoprotein C4 domain. The sequence of the HIV-1 JR . FL gpl20 C4 domain is: TLPCRIKQIINMWQEVGKAMYAPPIRGQIRCS- SNITGLLLTRDGG. The mutant HIV-l gpl20 envelope glycoprotein may be a mutant HIV-lj R-FL gpl20 envelope glycoprotein. HIV-I LAJ is a laboratory-adapted strain that is tropic for phytohemagglutinin (PHA) -stimulated peripheral blood lymphocytes (PBLs) and immortalized human T-cell lines. In contrast, HIV-l ra-FL was isolated from brain tissue taken at autopsy that was co-cultured with lectin-activated normal human PBLs. HIV-1 JR . FL is tropic for PHA-stimulated PBLs and blood-derived macrophages but will not replicate in transformed T-cell lines. Mutant HIV-l gpl20 envelope glycoproteins derived from a clinical isolate of HIV-l such as JR-FL may possess new or different epitopes compared to the laboratory-adapted HIV-l strains that are beneficial for successful vaccination. Although only the HIV-l^ and HIV- -L JR - FL strains are used herein to generate the mutant HIV-l gpl20 envelope glycoproteins of the subject invention, other HIV-l strain could be substituted in their place as is well known to those skilled in the art. The VI and V2 variable regions of gpl20 are unnecessary for CD4 binding (21) . Therefore the mutant HIV-l gpl20 envelope glycoprotein of this invention can either include or exclude the VI and V2 variable regions.

The subject invention additionally provides a recombinant nucleic acid molecule which encodes a mutant HIV-l gpl20 envelope glycoprotein comprising (a) a V3 loop deletion, or (b) a one of the C2, C3 or C4 domain point mutations discussed supra. The point mutations in the recombinant nucleic acid molecules described supra are selected based on their ability to reduce the affinity of the mutant gpl20 glycoprotein encoded thereby for CD4. As used herein, the term "reduce the affinity" means to reduce the affinity by at least two-fold. One skilled in the art would know how to make recombinant nucleic acid molecules which encode mutant HIV-l gpl20 envelope glycoproteins comprising a V3 loop deletion and the specific C2, C3 or C4 domain point mutations corresponding to those mutations exemplified in the HIV-I JR . FL and HIV-l^ strains, supra. Furthermore, one skilled in the art would know how to use these recombinant nucleic acid molecules to obtain the proteins encoded thereby, and practice the therapeutic and prophylactic methods of using same, as described herein for the recombinant nucleic acid molecule which encodes a mutant HIV-l gpl20 envelope glycoprotein comprising a V3 loop deletion and a C4 domain (W _ >X) point mutation. The subject invention also provides the mutant HIV-l gpl20 envelope glycoprotein encoded by the recombinant nucleic acid molecule of the subject invention. In accordance with the invention, numerous vector systems for expression of the mutant HIV-l gpl20 envelope glycoprotein may be employed. For example, one class of vectors utilizes DNA elements which are derived from animal viruses such as bovine papilloma virus, polyoma virus, adenovirus, vaccinia virus, baculovirus, retroviruses (RSV, MMTV or MoMLV) , Semliki Forest virus or SV40 virus. Additionally, cells which have stably integrated the DNA into their chromosomes may be selected by introducing one or more markers which allow for the selection of transfected host cells. The marker may provide, for example, prototropy to an auxotrophic host, biocide resistance, (e.g., antibiotics) or resistance to heavy metals such as copper or the like. The selectable marker gene can be either directly linked to the DNA sequences to be expressed, or introduced into the same cell by cotransformation. Additional elements may also be needed for optimal synthesis of mRNA. These elements may include splice signals, as well as transcriptional promoters, enhancers, and termination signals. The cDNA expression vectors incorporating such elements include those described by Okayama (22) . The vectors used in the subject invention are designed to express high levels of mutant HIV-l gpl20 envelope glycoproteins in cultured eukaryotic cells as well as efficiently secrete these proteins into the culture medium. The targeting of the mutant HIV-l gpl20 envelope glycoproteins into the culture medium is accomplished by fusing in-frame to the mature N-terminus of the mutant HIV-l gpl20 envelope glycoprotein the tissue plasminogen activator (tPA) prepro-signal sequence. The mutant HIV-l gpl20 envelope glycoprotein may be produced by a) transfecting a mammalian cell with an expression vector for producing mutant HIV-l gpl20 envelope glycoprotein; b) culturing the resulting transfected mammalian cell under conditions such that mutant HIV-l gpl20 envelope glycoprotein is produced; and c) recovering the mutant HIV-l gpl20 envelope glycoprotein so produced. Once the expression vector or DNA sequence containing the constructs has been prepared for expression, the expression vectors may be transfected or introduced into an appropriate mammalian cell host. Various techniques may be employed to achieve this, such as, for example, protoplast fusion, calcium phosphate precipitation, electroporation or other conventional techniques. In the case of protoplast fusion, the cells are grown in media and screened for the appropriate activity. Expression of the gene encoding a mutant HIV-l gpl20 envelope glycoprotein results in production of the mutant glycoprotein. Methods and conditions for culturing the resulting transfected cells and for recovering the mutant HIV-l gpl20 envelope glycoprotein so produced are well known to those skilled in the art, and may be varied or optimized depending upon the specific expression vector and mammalian host cell employed. In accordance with the claimed invention, the preferred host cells for expressing the mutant HIV-l gpl20 envelope glycoprotein of this invention are mammalian cell lines. Mammalian cell lines include, for example, monkey kidney CVl line transformed by SV40 (COS-7) ; human embryonic kidney line 293; baby hamster kidney cells (BHK) ; Chinese hamster ovary-cells-DHFR (CHO) ; Chinese hamster ovary-cells DHFR" (DXBll) ; monkey kidney cells (CVl) ; African green monkey kidney cells (VERO-76) ; human cervical carcinoma cells (HELA) ; canine kidney cells (MDCK) ; human lung cells (W138) ; human liver cells (Hep G2) ; mouse mammary tumor (MMT 060562); mouse cell line (C127) ; and myeloma cell lines.

In order to facilitate an understanding of the Experimental Details section which follows, certain frequently occurring methods and/or terms are best described in Maniatis et al. (23). This invention will be better understood by reference to the Experimental Details which follow, but those skilled in the art will readily appreciate that the specific experiments detailed are only illustrative of the invention as described more fully in the claims which follow thereafter. Experimental Details Nomenclature As used herein, V3° indicates a V3 loop deletion from HIV-l gpl20 envelope glycoprotein. As used herein, CD4 indicates a point mutation in the C4 domain of HIV-l gpl20 envelope glycoprotein which mutation inhibits CD4 binding to the mutant HIV-l gpl20 envelope glycoprotein. The structure of HIV-l gpl20 envelope glycoprotein is shown in Figure 1. Materials and Methods 1• Construction of PPI4-tPA-gp!20 LΛI expression vector. An expression vector was constructed that consisted of the cytomegalovirus major immediate early (CMV MIE) promoter/enhancer linked to the HIV-l LA jejnv gene, which gene had its signal sequence replaced by the tPA signal sequence. The CMV MIE promoter/enhancer sequences were derived from pSVCCl (24) consisting of 1580 base pairs of contiguous DNA that is immediately 5' to the initiator ATG. In sequential order, the functional domains of the CMV promoter are: the promoter/enhancer region; a transcriptional initiator site; exon A (a non-coding exon) ; intron A; and 17 nucleotides of exon B (non-coding sequences) . The viral promoter sequences were ligated to a gene construct consisting of the nucleotide sequences encoding amino acids -35 to -1 of human tPA (25) fused in-frame to HIV-l LΛI env amino acids 31 through 515, ending with a TGA stop codon. The construction was performed in two parts. The majority of the CMV promoter could be isolated as a 1560 bp Hinc II/Pst I fragment which was ligated to a Pst I/Not I 1590 bp DNA fragment that contained the remainder of the CMV promoter, the initiator ATG, the tPA signal sequence and the mature HIV-l^ env protein coding sequence. The latter fragment was assembled using the polymerase chain reaction as follows. Primer 1 (GATCCTGCAGTCACCGTCCTTGACA- CGATGGATGCAATGAAGAGA) and primer 2 (AAGTCTTCTCCTCGGTCTTGT- CTTTTTAACACCCAG) were used to amplify the nucleic acid sequences encoding the tPA signal sequence amino acids -35 to -1 from plasmid pMAM neo-s (Clonetech) , thus producing a 150 bp fragment. A second 1440 bp DNA fragment was amplified using primer 3 (TTCAGAAGAGGAGCCAGAACAGAAAAATTGTGGGTC) , primer 4 (GGAAAAAAGCGGCCGCTCATTTTTCTCTCTGCACCACTC) , andpENV (26) as a template. The PCR fragments were pooled, desalted, and excess primer removed by ultrafiltration through a centricon-100 unit (Amicon) . An aliquot of the pooled material was then subjected to a second round of amplification in the presence of primers 1 and 4 to produce a 1590 bp fragment, which was then digested with Pst I and Not I. The CMV promoter fragment and the HIV-1^ env fragment were then ligated together, and the entire transcription unit subcloned into PPI4, which is a eukaryotic shuttle vector that contains an ampicillin resistance gene, an SV40 origin of replication and a DHFR gene whose transcription is driven by the β-globin promoter. The final construct, PPI4-tPA-gpl20 LA ι, is shown in Figure 2. The expression vector is then used as the prototype vector for the expression of gpl20 proteins that are derived from other HIV-l strains or mutated as described in the methods section. The vector was constructed so that unique Nar I and Not I sites flank the gpl20 sequence, thus facilitating the removal of the gpl20 gene cassette and the subsequent insertion of other gene cassettes (Figure 2) . 2. Expression of HIV-l^gp!20 in mammalian cells. a. Transient expression. CosM5 cells grown in DMEM containing 10% fetal calf serum were split to 75% confluence. On the following day, the cells were transfected for 16-20 hours with 10 micrograms of CsCl-purified PPI4-tPA-gpl20 LAI DNA by the standard CaP0 4 (5) precipitation technique. After transfection, fresh medium was added to the cells. Analysis of the products synthesized 96-120 hours post-transfection was performed by radiolabelling the transfectants with 35 S-cysteine for 12-18 hours, followed by precipitation of media using a CD4- immunoglobulin-ProteinA-Sepharose complex, followed by SDS- PAGE under reducing conditions (Figure 4) . b. Stable expression. Dhfr " Chinese hamster ovary cells (CHO) were transfected with 20 micrograms of CsCl-purified DNA. Approximately 3-5 days post-transfection, cells were placed in selective medium (nucleoside-free alpha MEM containing 10% dialyzed fetal calf serum) . Approximately 10-15 days post-selection, individual cell clones were picked. Media was analyzed for gpl20 expression by radiolabelling the cells with 35 S- cysteine for 12-18 hours, followed by precipitation of media using a CD4-immunoglobulin-Protein A-Sepharose complex, followed in turn by SDS-PAGE under reducing conditions (Figure 6) . The levels of gpl20 in the media of these clones were also quantitated (Figure 5) by ELISA performed as follows. The method involves coating 96-well plates overnight with sheep polyclonal IgG against the highly conserved C-terminus of gpl20 (D7234, Aalto Bioreagents) . After washing, dilutions of a standard gpl20 preparation in cell growth medium, or supernatant from the stably- transfected cells, were incubated for l hour. The plates were washed again, and incubated for one hour with a horseradish peroxidase-conjugated anti-gpl20 monoclonal antibody (9204, DuPont) . Following a final wash, the peroxidase substrate OPD (DuPont) was added and the amount of gpl20 determined by comparing absorbance of unknowns with a standard curve. Standards were prepared from purified gpl20 made in CHO cells, a small quantity of which was obtained from Celltech Ltd. Clones expressing the highest levels were subjected to successive rounds of amplification of the newly introduced DNA sequences in increasing concentrations of methotrexate. Stable CHO cell lines were thus generated which secrete at least 1 microgram/milliliter of HIV-I LAJ gpl20. 3. Construction of PPI4-tPA-gpl20 mFL a. The HIV-I LA! gpl20 env nucleotide sequence in PPI4-tPA- gpl20 LAI was replaced by the nucleotide sequence encoding the mature gpl20j R .p L protein. Using the polymerase chain reaction, the JR-FL sequences were amplified from pUC112-l (27) using primer 5 (GATCGGCGCCAGAGTAGAAAAGTTGTGGGTCAC) and primer 4. The PCR fragment was digested with the restriction endonucleases Nar I and Not I, and the fragment subcloned in between the Nar I and Not I sites in PPI4-tPA- gpl20 LA i to generate PPI4-tPA-gpl20 JR . PL (Figure 7) . b. Transient expression. CosM5 cells grown in DMEM containing 10% fetal calf serum were split to 75% confluence. On the following day, the cells were transfected for 16-20 hours with 10 micrograms of CsCl-purified PPI4-tPA-gpl20 JR .p L DNA by the standard CaP0 4 (5) precipitation technique. After transfection, fresh medium was added to the cells. Analysis of the products synthesized 96-120 hours post-transfection was performed by radiolabelling the transfectants with 35 S-cysteine for 12-18 hours, followed by precipitation of media using a CD4- immunoglobulin-Protein A-Sepharose complex, followed by SDS- PAGE under reducing conditions (Figure 4) . 4. Construction of PPI4-tPA-gpl20 L ^-V3 H . The V3 loop in tPA-gpl20 LAI consists of amino acids Cys 306 through Cys 333 . In the V3 ri mutant, the amino acids in between these cysteines are replaced by the pentapeptide sequence Thr-Gly-Ala-Gly-His. Using the Transformer Site- Directed Mutagenesis Kit (Clonetech) , the V3 loop sequence in PPI4-tPA-gpl2θ LA i is altered using the mutagenic primer 6 (CTGTAGAAATTAATTGTACAGGTGCTGGACATTGTAACATTAGTAGAGC) and primer 7 (CTCGAGCATGCATTCGAAGCTCGCTGATC) as a selection primer. Primer 7 changes a unique Xba I site in the backbone of the parent PPI4 plasmid into a unique BstB I site. Briefly, the mutagenesis method requires incubating of the parent plasmid with the mutagenic primer and the selection primer, denaturing at 100°C for 3 minutes and then chilling on ice. In the presence of buffered deoxynucleo- tide triphosphates and T4 DNA polymerase, the primers are allowed to initiate the polymerization of one strand of plasmid DNA. T4 DNA ligase is used to seal the newly synthesized DNA strand to form a covalently closed circle. Hybrid plasmids are then transformed into a MutS strain of E. coli that is deficient in mismatch repair. After allowing for the growth of transformed cells, DNA is purified from the cells and digested with the selection restriction endonuclease, in this case Xba I. Parental plasmids are cleaved by Xba I while the mutant plasmid remains resistant to cleavage by virtue of the Xba I to BstB I conversion. Digested DNA is then used to transform E. coli. and colonies harboring the mutant plasmid are picked. Multiple mutagenic primers can be used in a single round of mutagenesis. The amino acid sequence of the modified protein is shown in Figure 8. 5 . Construction of PPI4 - tPA-gpl20 m FL -V3 ( ' ) . The V3 loop in tPA-gpl20 JR .

On the next day, the cells are transfected for 16-20 hours with 10 micrograms of CsCl- purified mutant HIV-l DNA by the standard CaP0 4 (5) precipitation technique. After transfection, fresh medium is added to the cells. Analysis of the products synthesized 96-120 hours post-transfection is performed by radiolabelling the transfectants with 35 S-cysteine for 12-18 hours, followed by precipitation of media using a sheep polyclonal IgG against the highly conserved C-terminus of gpl20. b.

Approximately 3-5 days post-transfection, cells are placed in selective medium (nucleoside-free alpha MEM containing 10% dialyzed fetal calf serum) . Approximately 10-15 days post-selection, individual cell clones are picked. Media is analyzed for gpl20 expression by radiolabelling the cells with 35 S- cysteine for 12-18 hours, followed by quantitative immunoprecipitation of media using a sheep polyclonal IgG against the highly conserved C-terminus of gpl20, followed in turn by SDS-PAGE under reducing conditions. Alternatively, one can quantitate the level of gpl20 by ELISA performed as follows. The method involves coating 96- well plates overnight with sheep polyclonal IgG against the highly conserved C- erminus of gpl20 (D7234, Aalto Bioreagents) . After washing, dilutions of a standard gpl20 preparation in cell growth medium, or supernatant from the stably-transfected cells, are incubated for 1 hour. The plates are washed again, and incubated for one hour with a human MoAb (F105, AIDS Research & Reference Reagent Program, No. 857) . The plates are washed again, and incubated again for 1 hour with a horseradish-peroxidase-conjugated goat anti-human IgG (Cappel) . Following a final wash, the peroxidase substrate OPD (DuPont) is added and the amount of gpl20 determined by comparing absorbance of unknowns with a standard curve. Standards are prepared from purified gpl20 made in CHO cells, a small quantity of which is obtained from Celltech Ltd. Clones expressing the highest levels are subjected to successive rounds of amplification of the newly introduced DNA sequences in increasing concentrations of methotrexate. Stable CHO cell lines are thus generated which secrete at least 1 microgram/milliliter of mutant HIV- l gpl20. 11. Purification of HIV-l gp!20 proteins. A one-step immunoaffinity procedure is used to purify the recombinant gpl20 molecules described. Briefly, culture supernatant is collected and clarified by centrifugation. An immunoaffinity column consisting of a matrix coupled to a sheep polyclonal anti-gpl20 IgG (D7234, Aalto Bioreagents) directed against the highly conserved C-terminal end (APTKAKRRWQREKR) of gpl20 is used to specifically adsorb gpl20 from the cell culture media. This antisera recognizes native gpl20, the V3 loop deletion mutants, and the CD4 W mutants since the C-terminal ends of these molecules remain unaltered. The bound gpl20 is then eluted with 2M MgCl 2 , concentrated by Amicon filtration, and dialyzed into 10 mM HEPES, pH 7.0. The purity of the proteins is determined by SDS-PAGE and silver staining. 12. Characterization of recombinant HIV-l gp!20 proteins. The purified glycoproteins are subjected to extensive biochemical and immunologic characterization. The integrity of the proteins is monitored by SDS-PAGE and silver staining under reducing and non-reducing conditions. The glycoproteins are deglycosylated by treatment with the enzyme N-glycosidase F which cleaves N-linked oligo- saccharides, and are assayed by SDS-PAGE and silver staining to ' monitor molecular weight shifts. The purified glycoproteins are also tested for reactivity with several well characterized anti-gpl20 monoclonal antibodies that recognize both linear and discontinuous epitopes. The binding affinity to sCD4 is estimated using an ELISA assay. The purified proteins HIV-l gpl20LAi# gP^ -LAi-V^ > gP 12 0__Ar v 3 (~ ) -CD4 ( -\ gpl20j R . PL , plSOj R . PL -VS , and gpl20j R . FL -V3 ( - ) -CD4 ( - ) , were tested for their ability to bind cell surface human CD4. DG44 #3 cells, a recombinant cell line designed to express human CD4 on the membrane surface, were grown in T flasks and trypsinized. 5 X 10 5 cells/experiment were aliquoted into FACS buffer (PBS + 2% BSA and 0.1% NaN 3 ) , washed several times in the same buffer, and then incubated with 100 ul of a solution of purified gpl20 protein at 5ug/ml in FACS buffer at 37°C for 2 hr. The cells were washed in FACS buffer, and then incubated in 100 ul solution containing 5ug/ml sheep polyclonal IgG against the highly conserved C- terminus of gpl20 in FACS buffer at 37°C for 2 hr. The cells were washed in FACS buffer then incubated in 100 ul solution containing FITC-labeled rabbit anti-sheep IgG polyclonal antibody at 37°C for 2 hr. The cells were washed with FACS buffer and then resuspended in 500 ul FACS buffer. The cells were then analyzed on a Becton Dickinson FACScan according to the manufacturer's instructions. As a control for expression of CD4 on the DG44 #3 cells, FITC-labeled 0KT4A (Becton Dickinson) was used. 13. A protocol for inoculation of animals with the mutant HIV-l gp!20 envelope glycoproteins. Alum is used as an adjuvant during the inoculation series. The inoculum is prepared by dissolving the mutant HIV-l gpl20 envelope glycoprotein antigen in physiologic saline at a final antigen concentration of 100 ug/ml. Preformed alum (aluminum hydroxide gel) is added to the solution to a final level of 500 ug/ml aluminum. The antigen is allowed to adsorb onto the alum gel for two hours at room temperature. Following adsorption, the gel with the antigen is washed twice with physiologic saline and resuspended in the saline to a protein concentration of 100 ug/ml. Monkeys and/or Guinea Pigs are individually inoculated with four 100 ug doses of the mutant HIV-l gpl20 envelope glycoprotein antigen adsorbed onto alum. Each dose is injected intramuscularly. The doses are delivered one or five months apart (week 0, 4, 8 and 28) . the animals are bled at intervals of two or four weeks. Serum samples are prepared from each bleed to assay for the development of specific antibodies as described in the subsequent sections. 14. Analysis of sera for anti-mutant HIV-l gpl20 envelope glycoprotein IgG antibodies. Each serum sample is analyzed by ELISA. Polystyrene microtiter plates are coated with 0.5 ug per well of pure mutant HIV-l gpl20 envelope glycoprotein in phosphate- buffered physiological saline (PBS) at 4°C. Each well is then washed with PBS containing 0.5% T EEN-20 (PBS-TW) . Test serum, diluted serially in PBS-TW, is added to the mutant HIV-l gpl20 envelope glycoprotein-containing wells and allowed to react with the adsorbed mutant HIV-l .gpl20 envelope glycoprotein for one hour at 37°C. The wells are then washed extensively in PBS-TW. Each well then receives 0.1% p-nitrophenyl phosphate in 10% diethanolamine, pH 9.8, containing 0.5 mM MgCl 2 .6H 2 0. The ensuing reaction is allowed to proceed at room temperature for 30 minutes, at which time it is terminated by the addition of 3.0 N NaOH. The greater the interaction of antibodies in the test serum with the mutant HIV-l gpl20 envelope glycoprotein, the greater is the amount of alkaline phosphatase bound onto the well. The phosphatase enzyme mediates the breakdown of p- nitrophenyl phosphate into a molecular substance which absorbs light at a wavelength of 405 nm. Hence, there exists a direct relationship between the absorbance at 405 nm of light at the end of the ELISA reaction and the amount of mutant HIV-l gpl20 envelope glycoprotein-bound antibody. All animals inoculated with mutant HIV-l gpl20 envelope glycoprotein whose serum reacts specifically with the mutant HIV-l gpl20 envelope glycoprotein in the ELISA have a positive antibody response against mutant HIV-l gpi20 envelope glycoprotein. 15. Analysis of sera for activity which specifically neutralizes HIV-l infectivity. Virus-neutralizing activity is determined with an assay based on the use of multiplicity curves in which the ratio of infectious virus surviving antibody treatment (V n ) is compared to infectious virus in uninhibited cultures (V„) at various dilutions of antisera. The neutralization titer of the sera is then interpolated as that sera dilution which yields one log reduction in infectious titer (i.e., V n /V 0 = 0.1). Briefly, 4-fold dilutions of virus (laboratory- adapted and primary isolates) are prepared to yield infectious doses of 0.1 to 100 TCID 50 (Tissue Culture Infection Dose) in 20 ul. Serial 3-fold dilutions of sera are also prepared and 20 ul of each serum dilution are incubated with each dilution of virus in duplicate for 60 minutes at room temperature in a 96-well microtiter plate. 20 ul of AA5 cells (PHA stimulated PBMCs for primary HIV-l isolates) are then added to the serum/virus mixtures. Cells are cultured for 7 days by the addition of fresh medium every other day. On the seventh day, supernatant from each well is removed and tested for the presence of reverse transcriptase (RT) . Infection in each well is then scored as either positive or negative based on the RT counts, and the infectious dose of virus in each treatment group is calculated using the Reed and Muench (28) formula. The neutralization titers represent the reciprocal serum dilution required to reduced infectious dose of virus by one log. The above culture time is for the prototypic HIV-l^ isolate tested on the AA5 cell line. In the case of primary isolates, the termination date is usually 11-14 days. Culture conditions for PBMCs is not as demanding since doubling time is restricted. In the case of PBMCs, one day PHA stimulations are used at a final concentration of 1.5 X lOVml on day 0. Half that number of fresh PBMCs are then added again on days 4 and 8. This multiple addition of PBMCs is meant to amplify virus output upon successful infection so that the readout RT signal is strong. Again, the final readout titer for the primary isolate/PBMC is the reciprocal serum dilution which reduces infectious titer by one log. 16. Passive hyperimmune therapy. Non-HIV-1-infected humans are immunized with the mutant HIV- 1 gpl20 envelope glycoprotein antigens according to a protocol similar to that described above in section 12. For passive hyperimmune therapy in HIV-l-infected individuals, blood plasma is taken from mutant HIV-l gpl20 envelope glycoprotein immunized, non-HIV-l-infected human donors whose plasma has high levels of neutralizing antibodies. The plasma is pooled from several donors, purified to remove nonimmunoglobulin proteins and is then sterilized to kill any other viruses or pathogens. The treated plasma is then injected into individuals infected with HIV-l, with repeated injections every week, every two weeks, or every month. Results Eukaryotic expression vectors designed to express high levels of HIV-l^ gpl20 and HIV-1 /R . FL gpl20 were constructed. The CMV MIE promoter/enhancer was used to drive, the transcription of a gene fusion consisting of the human tPA signal sequence fused to mature gpl20 (Figures 2 and 7) . The complete sequence of the transcription unit from the Hinc II site of the CMV promoter/enhancer to the Not I site just 3' from the stop codon in gpl20 is shown in figure 3. This vector was used to transfect C0SM5 cells in a transient assay. The transfected cells were labeled with 35 S-cysteine and the media immunoprecipitated with a CD4-immunoglobulin- Protein A-Sepharose complex. The precipitated products were analyzed using a reducing 10% SDS-PAGE gel and autoradiography (Figure 4) . A 120 kD band was detected when PPI4-tPA-gpl2θ LA i was used to transfect COS cells (lane 3) . A band migrating with a slightly lower molecular mass was detected when PPI4-tPA-gpl20 R .p L was used to transfect COS cells (lane 4) . No radiolabeled products were detected in the mock infected cells. Using a sheep polyclonal antibody directed against the highly conserved C-terminal end of HIV- 1 gpl20 in an ELISA assay, the level of expression of HIV-l gpl20 was determined to be 2350 ng/ l. The PPI4-tPA-gpl20 IJU vector was then used to stably transfect the dhfr " CHO cell line DXBll. Two days post- transfection, the cells were plated at low density in nucleoside-free medium. Eight days post-transfection, surviving clones were isolated and expanded. Individual primary transfectants were tested for gpl20 expression using the ELISA method described in the methods section. Several primary CHO transfectants expressed significant quantities (10-120 ng/ml) of gpl20 (Figure 5) . Three of the highest expressing clones were then subjected to increasing concentrations of methotrexate in order to amplify, in tandem, the copy number of the dhfr and gpl20 genes. Cell lines were established that express high levels of gpl20 with rates of secretion greater than 1 mg/liter. These were then used to purify gpl20 to homogeneity. Six CHO cell lines were established, using the procedures uc-. ^i -.JJCU -Lii .Lin. me ι_.i.-.u<__.-_> acu j-ύπa , UHCI L CΛ l css ul^u C C- S of the following proteins: HIV-l gpl20 LA i# gp^O^-VS 0 , gpl20 LA1 -V3 ( - ) -CD4 ( - ) , gpl20j R . FL , gpl20j R . FL -V3 ") , and gpl20j R . FL -V3 w - CD4°. Metabolic labeling of these cells with 35 S-cysteine followed by immunoprecipitation with the human monoclonal antibody F105 and analyzed by SDS-PAGE and autoradiography showed the presence of the gpl20 proteins in the culture supernatant (Figure 14) . From these cell lines the gpl20 proteins were purified to homogeneity. Analysis by SDS-PAGE followed by silver-staining showed the purity of these proteins to be greater than 90% (Figure 15) . It was shown by FACScan analysis that the two CD4 binding mutants HIV-lgpl20 LAI -V3 ( - ) -CD4 ( - ) and HIV-l gpl20 JR . FL -V3 ( - ) -CD4 ( - had no appreciable binding to recombinant cell lines designed to express high levels of human CD4 on their membrane surface (Figure 16, panel 4 and data not shown, respectively) . Discussion The advantage of using the mutant HIV-l gpl20 envelope glycoproteins as immunogens is that these proteins will not elicit an immune response against the V3 loop, a highly immunodominant epitope on gpl20. This is significant because the V3 loop may skew the humoral immune response away from discontinuous epitopes in the CD4-binding site. Mutant HIV-l gpl20 envelope glycoproteins having partial and total V3 loop deletions have been made (30) . Deletion of the V3 loop therefore exposes the CD4-binding site to the immune system, allowing the immune system to mount a response against this critical region (18) . Another advantage of using the mutant HIV-l gpl20 envelope glycoprotein as an immunogen is that it has significantly reduced affinity for cell surface CD4. An efficient humoral immune response depends on the binding of antigen to B cell surface immunoglobulin. The presence of the high-affinity CD4 receptor on large numbers of cells in the body may significantly diminish the ability of native gpl20 to induce an effective humoral immune response. The rationale of mutating gpl20 at the CD4 binding site is to redirect the mutant HIV-l gpl20 envelope glycoprotein away from cell surface CD4 toward immunoglobulin-bearing B cells, thereby allowing the immune system to mount a response against, inter alia, the CD4-binding site.
